"A statistical analysis shows that icons with less detail score better in terms of usability. It seems to be an easy truth: too much detail in icons confuses the users. So we wondered whether we could find any evidence for this truth in the data of our large scale test of the LibreOffice Icons."

Maybe the point is: LibreOffice, and similar projects, will have utter shit design as long as they have wanks wasting their time with pseudo-scientific studies that don't even measure what they think they are measuring but belying their complete lack of design skills and usability testing skills? Maybe, I don't know.
